Thousands of supporters attended Republican nominee Donald Trump’s campaign event outside of outside of Harrisburg, Pennsylvania on Monday. But what started out as a peaceful protest of anti-Trump advocates quickly devolved into a shouting match, calling Trump supporters racists.

The small group of protesters were polite and encouraged those entering the rally site to “enjoy the event.” Instead of a “thanks” they were met with insults and snide remarks.

“Our message is that we want everyone to love each other,” said protester Lindsey Knause, a graduate of the school where the rally was being held. She stood among signs saying “free hugs” and others advocating for peace. “We don’t want to spread hate like he is doing.”

According to PennLive, protesters tried to be friendly and respectful of the passersby, but it was the Trump supporters that began yelling at them. The protesters could only take so much.

After approximately three hours, thousands of Trump supporters were turned away from the rally because the event reached capacity. The anti-Trump protesters began shouting “You’re racists” at the Trump supporters, who shouted back, “Get a job!” and “Stop living off the government.”

Police intervened and stood between the two groups with batons ready if the fight got physical.

Anti-Trump protester Dan Seiple was visiting his parents in the town when he learned of the protest at the school. He was bothered by the fact that the school would allow Trump to hold a rally on campus.

“I was pretty appalled to see my alma mater was hosting this event,” he said. “I’m freaked out that this is even going on. I question the education I received here.”
